IMPROVEMENT IN CARRIAGE-AXLE BOXES.

Specification forming part of Letters Patent No. 114,148, dated April25, 1871.

' other vehicles of hard-rolled sheet-brass or other suitable material,whereby I am enabled to produce a neater, lighter, and cheaper articlethan by the old casting process.

To enable others skilled in the art to make and use my invention, I willnow proceed to describe its construction, referring to the accompanyingdrawing, and to theletters marked thereon.

Figure 1 represents a side elevation of my box. Fig. 2 is a longitudinalsection of the same. Fig. 3 is a transverse section of the box, taken onthe line as y, Fig. 2.

In the construction of my axle-boxes A, I take a blank form ofhard'rolled sheet-brass or other suitable hard metal and put it in thedies, where it is shaped into the proper form.

It is then taken to another press, where'the collar B is formed upon theinner end. fIhe joint where the two ends of the metal meet are brazedtogether, and, without further work, the boX is ready for use.

By the old process the box had first to be cast, then bored out, itsouter surface turned, and then its ends be cut squarely ofi.

As the sheet metal which I use is rolled so as to be equally smooth onboth sides, and as the (lie stamps the forms into proper shape, thecasting, boring, turning, and shaping the ends are all dispensed with,and 1 produce an article which is not only far cheaper, but lighter andneater, than those which are cast.

In making the boxes I prefer to use hardrolled sheet-brass, as beingtougher, and better adapted to withstand the friction of the axle; but,if desired, other hard-rolled metal may bensed in its place.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is i 1. The carriage-axle box A, formed ofhardrolled sheet-metal, substantially as shown and described.

2. As a new article of manufacture, an axlebox constructed ofhard-rolled sheet-brass or other suitable material, substantially asspecified.
